OAKLAND, Calif. 
Authorities have identified one of the victims of a fatal shooting at an Oakland nightclub as a 22-year-old San Leandro resident.

Adam Williams was among two people who were shot to death when a gunman opened fire inside Sweet Jimmie's in Jack London Square just before 1 a.m. Monday. The San Francisco Chronicle reports that Williams worked at an after-school program at Peralta Elementary School in Oakland.

The name of the other victim, a 27-year-old Oakland man, has not been released.

Police say the shooter entered the club and opened fire indiscriminately with an assault rifle. There were about 10 to 15 people inside at the time.

Four others were injured, two of them critically.

Police believe the shooter, who remains at large, was among four men in their late teens or early 20s driving a four-door white Dodge Avenger.
